CORALS FROM THE DEVONIAN FORMATION. 243 



Corallum composite, forming almost flat masses. Calices slightly prominent and 

 placed at unequal distances (in general about \\ their diameter). Costce irregularly con- 

 fluent, large, rather thin, equally developed, flexuous or geniculated, delicately crenulated, 

 and closely set (about a quarter of a line apart) ; 15 or 16 principal ones slightly exsert, 

 terminated by an arched edge, extending almost to the centre of the visceral chamber, 

 where they become very slender, bearing a small paliform lobe and alternating with an 

 equal number of small septa ; wall well developed, rather thick. Columella appearing to 

 be slightly compressed. Diameter of the calices 1^ line ; depth almost half a line. 



Found at Torquay; and at Valcos in the province of Leon in Spain. 



In the Collection of the Geological Society of London, &c. 



This species differs from S. organuiii)- and 8. Torrearmm" by the costal radii being more 

 numerous and more confluent.

Corallum simple, very long, slightly bent, subcylindrical, provided Avith a very strong 

 epitheca, and presenting rather strong subhorizontal circular wrinkles. Caliciilar cavity 

 rather deep ; the septal striae, when visible, more distinct towards the outer part of the 

 calice. Vesicules unequal in size ; the largest occupying the centre of the visceral cavity 

 and about 1 hue in length. Height of the coral in general about 3 or 4 inches. We ha\ c 

 seen in the collection of Mr. Pengelly a specimen that measured above 1 foot in length, 

 and 1^ inch in diameter. 



The British specimens submitted to our examination were found at Torquay, Plymouth,
